Y=14.5
X= 5
Hope this helps :)
The answer is A. h + 3s = 35 and 2h + s = 20
Just write it out and make the sides equal to 37 like shown here. Have a great day/night!!
A=<4.60,7.20>
b=<5.10,2.70>
The scalar product, or the inner product, or the dot-product, is by summing the products of the respective directions,
a.b=4.6*5.1+7.2*2.7
=23.46+19.44
=42.9
